SOLVENT: development of strategies for the efficient use of solar and passive ventilation in urban buildings. | 2001 | English
In the framework of SOLVENT project, work was carried out to develop strategies and dissemination material to assist the efficient application of solar and passive ventilation in urban buildings.
The Building Regulations with regard to the energy performance of buildings in the Netherlands is an attempt to a performance oriented requirement in conjunction with a test standard. The test standard in fact means a calculation procedure.
The International Space Station (ISS) is the biggest multinational space program ever with 16 countries involved. Since November 2000 the station is permanently occupied with a crew of 3 astronauts.
Experimental study on the impact of ventilation parameters on pollutant transfer from outdoor air into a dwelling. | 2001 | English
In urban areas, people stand the most of their time in indoor environment. In this context, indoor air quality is more and more a subject of concern. Outdoor air quality can have a large impact on indoor air quality.
Increased global warming and deterioration of the ozone layer have stimulated interest in the use of renewable energy systems.
The main problem in natural ventilation is that its efficiency depends very tightly on the meteorological conditions : high wind velocity and outside temperature lower than inside are optimal conditions for efficient ventilation.
Overview of key aspects in the proposed energy performance regulation for the Flemish Region in Belgium. | 2001 | English
It is expected that there will be in 2003 an energy performance regulation for the Flemish Region. In the framework of the VLIET-EPIGOON project, a proposal for such legislation is under preparation.
Airtightness of 12 non residential large buildings. Results from field measurement studies. | 2001 | English
We investigate the airtightness of 12 French non-residential buildings, by means of experimental fan-depressurization tests.
Earth-air heat exchangers in the Belgian climate: Analysis of the potential with a 3D modelling technique. | 2001 | English
Earth-air heat exchangers can be used to reduce energy consumption in building ventilation systems. The idea is to pre-heat air in winter and pre-cool air in summer using the thermal capacity of the soil.
In this paper, measurement and simulation results are presented that demonstrate the energy performance of a recently built ecological house in Helsinki, Finland.
Air filters may be used to reduce indoor airborne concentration which is one of the main indoor air pollutants. Air filters performances have to be measured in order to be able to select the right product for a given application.
Energy performance standardisation and regulation: state-of-the-art, challenges and ongoing actions. | 2001 | English
Energy Performance standardisation and legislation is receiving an increased interest in many countries.
This paper illustrates the airtightness and ventilation performance of a recently built ecological house in Helsinki, Finland.
Energy conservation in buildings with integration of advanced ventilated wall components. | 2001 | English
The performance of a Ventilated wall component under real weather conditions was tested, during two weather seasons, winter and summer.
The paper reviewed the supply opening models of describing inlet boundary conditions for indoor airflow simulation firstly. Then examples of isothermal free air jets from a grille are presented to validate full representation of supply openings.
Evaluation and development of innovative and energe efficient ventilation strategies. | 2001 | English
A potential conflict may exist between energy saving and good indoor climate.
In this study a parametric analysis was carried out of the interaction between louvres and various perforated mesh screens. This type of arrangement is common in through-the-wall ventilators used for natural ventilation in buildings.
This paper briefly exams the role of the building envelope in determining the internal environmental conditions in buildings and the scope for holistic design of building services and building envelope.
